After disappointing pricing on Mac Pro I'm thinking about building a workstation with Mac Mini. I watched some reviews and it seems that Mac Mini built-in cooling is barely keeps CPU from throttling and CPU gets quite hot, 90+ C. That's unacceptable for me. I need CPU to keep boosting at 4.5+ GHz for a prolonged time and keeping CPU at 70 C max. Obvious improvement is to use external fans cooling Mac Mini case itself. Did someone used that setup and did it improve cooling situation?
